BJP workers clashed with police in Kolkata as their march to the police headquarters demanding the arrest of "corrupt" TMC leaders turned violent prompting the force to use teargas shells, water canons and batons to disperse them.
BJP workers, who took out the procession towards the headquarters in Lalbazar area, were stopped by the police at Brabourne road.
The saffron party's workers then tried to break the barricades there to move forward, forcing the police to use force.
